WHEAT-SCOURING MACHINE.

Specification of Letters Patent.

Patented J an. 17, 1911.

Application filed February 25, 1910. Serial No. 545,827.

T 0 all whom it may concern:

Be it known that I, I'IENRY A. WALLIS, a

resident of Martin, in the county of VVeakley and State of Tennessee,have invented certain new and useful Improvements in lVheat-ScouringMachines, of which the following is a specification.

This invention relates to milling machin cry and particularly to a wheatscouring machine designed for the purpose of thoroughly scouring andcleaning wheat.

An object of this invention is to provide a machine to which thematerial is delivered at opposite ends thereof, means being provided forcarrying the material longitudinally of the machine to the centerthereof and for delivering it to a discharge spout.

Furthermore, an object of this invention is to provide a conveyer of thescrew type the portions of the conveyer on opposite sides of the machinebeing turned in opposite directions but the blades of the conveyer beingof the same pitch, thereby enabling the employment of left handconveyers on each side of the center, means being provided for rotatingthe sections of the conveyer in opposite directions.

A still further object of this invention is to produce a casing having adischarge opening guarded by a pressure door and in connection with thesaid opening, a discharge spout is also provided in order that materialdelivered at the ends of the machine may be taken therefrom at thecentral portion thereof and conducted to any ma chine or receptacledesigned for its admission.

Finally, an object of this invention is to produce an improvement inmilling maehin- I cry which will be simple in construction, efiicientinpractice and comparatively in expensive to manufacture.

IVith the foregoing and other objects in View, the invention consists inthe details of construction and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

I11 describing the invention in detail, reference will be had to theaccompanying drawings forming part of this specification wherein likecharacters denote corresponding parts in the several views in whichFigure 1 illustrates a View in elevation of the exterior of the scouringmachine embodying the invention; Fig. 3 illustrates a top plan viewthereof with the cover removed; Fig. 2 illustrates a view in eleva tionof one end of the machine; Fig. 4. illustrates a view in elevation ofthe opposite end thereof; and Fig. 5 illustrates a View in elevation ofone end of the machine shown in Fig. l with the end thereof removed andwith the shafts in section.

In these drawings A denotes the cover and B a casing or hopper to whichthe cover is applied. The hopper is provided with a shaft D and a shaftH which extend through the ends of the hopper and the sprocket wheel Cis mounted on one end of the shaft D, Whereas a spur gear E is mountedon the outer end of the shaft D. The sprocket wheel C has a sprocketchain F which runs on a sprocket wheel G mounted on a shaft H, whichshaft H is journaled in the frame I. The spur gear E meshes with thepinion K also on theshaft H and-a power wheel L is provided for drivingthe shaft H.

\Vithin the hopper E are two conveyers M and N, each of which has bladeswhich are of the left-hand type, one of the conveyers N taking motionfrom the sprocket wheel C and the other conveyor taking motion from thespur gear E. As the sprocket wheel C and the spur gear E are both drivenfrom the power shaft H, they will rotate in opposite directions andtherefore the conveyers M and N will likewise be rotated in oppositedirections, in order that both of the conveyers will feed or carrymaterial toward the center of the hopper.

The hopper is provided with an opening O guarded by a door P, which doorhas a lever Q, attached to it with a weight R on its outer end oradjustable longitudinally 1n order-to change its effectiveness. Thespout form a mouth T which is in such relation to the opening 0 of thehopper that material fed to the center of the hopper by the conveyerswill be forced out of the opening 0 and find its way into the mouth T ofthe spout S from whence it may be conducted to a bin or machine forfurther use.

In operation, it will be observed that the lever Q may be adjustedthrough the medium of the weight to control the door and that when themachine is in operation and material is delivered to it through thesupply pipes or spouts U which lead into the hopper through the top Aand that material so supplied will be acted on by the convey- I S hasits upper end flared or enlarged to ers as heretofore indicated, andthat by reason of the construction of the machine, grain may be treatedexpeditiously and inexpensively.

The shafts I) and D have their inner ends journaled in a bearing 6mounted on a cross bar 7; said cross bar being sup'ported.in the hopperat the sides of said hopper. The bearing 6, is provided with an oilsupply tube 8 which extends through the top of the hopper so that dustcannot reach the bearing through the oil tube to any appreciable degree.

I claim 1. In a wheat scouring machine, a hopper and a supporting frametherefor, a cover for the hopper, spouts leading into the hopper nearthe ends thereof, a shaft comprising two sections extending through thehopper, a conveyerhaving left-hand blades mounted on each of saidsections within the hopper, a door intermediate of the hopper to whichthe conveyers carry material, and means for rotating the conveyers,inopposite directions.

2. In a wheat scouring machine, a hopper and a supporting frametherefor, a cover for the hopper, spouts leading into the hopper nearthe ends thereof, a shaft comprising two sections extending through thehopper, a support located centrally in the hopper,

V the adjacent ends of the sections of said shaft being 'journaled inthe support, a conveyer having left-hand blades mounted on each of saidsections within the hopper, said hopper having a central opening thereinto which the conveyers carry material, a presthe adjacent ends of thesections of said shaft being journaled in the support, a conveyer havingleft-hand blades mounted on each of said sections within the hopper,said hopper having a central opening therein to which the conveyerscarry material, a pres sure door guarding the opening, a spout forreceiving material discharged through said opening, a gear fastened tothe other end of one section of the shaft, a sprocket wheel on the endof the other section, a second shaft journaled in the frame andextending parallel to the shaft in the hopper, a gear on the secondshaft meshing with the first mentioned gear, a sprocket wheel on thesecond shaft, a chain connecting the first mentioned sprocket wheel andthe sprocket wheel on the second shaft whereby a single source of'powerrotates the shafts in opposite directions.

In testimony whereof, I afiix my signature in the presence of twowitnesses.
